Cobalt Kinetics CK-Pro 5.56x45mm NATO 6.75" Receiver Set - CK Green Cerakote

The Cobalt Kinetics CK-Pro Receiver Set in CK Green Cerakote delivers a premium matched upper and lower foundation for builders assembling a custom AR-platform rifle chambered in 5.56x45mm NATO. Machined from aluminum and finished in Cobalt Kinetics' signature CK Green Cerakote, this set pairs rugged construction with the distinctive styling the brand is known for.

The set includes a matched upper receiver, lower receiver, and a 6.75" handguard providing a compact handling package suited to carbine, SBR, and pistol-length AR builds. Also included are the ejection port assembly, forward assist assembly, mounting hardware, jam nut, and jam nut installation tool, everything needed to complete the receiver assembly.

This is a serialized receiver set and not a complete firearm. To finish the build, the customer will need to supply a barrel, bolt and bolt carrier group, lower parts kit, stock or brace, pistol grip, muzzle device, optic, and a magazine. Once assembled, the CK-Pro receiver set forms the foundation of a feature-rich, accurate, and reliable AR-platform rifle ready for sport, duty, or defense applications.
